It is a new draining geosynthetics. It is made of high-density polyethylene (HDPE) and the ultravioresistant agent with the property of aging resistance and erosion resistance. It has three-layer special constructions.
3D complex drainage net used with geotextile,can reach the efficacy of inverted filter-drain-protect.Now It is the most perfact drain geosynthetics.
It is widly used on the rubbish-landfills,high way subfrade and pavement,railwy,tunnel,gardon,playfrounds and other underground structures.
